106 The first two digits contain the major release number,
107 the third and fourth digits the minor release number,
108 and the fifth and sixth digits the fix release number.
109 For OpenSSL, the seventh and eight digits contain the patch release number
110 and the final digit is 0 for development, 1 to e for betas 1 to 14, or f

131 OpenSSL versions prior to 0.9.3 had identifiers < 0x0930.
132 For versions between 0.9.3 and 0.9.5,
133 the seventh digit was 1 for release and 0 otherwise,
134 and the eighth and ninth digits were the patch release number.
138 0x000904100 == 0.9.4 release
139 0x000905000 == 0.9.5 dev
142 OpenSSL version 0.9.5a had an interim interpretation that is like the current
143 one, except the patch level got the highest bit set, to keep continuity.
144 The number was therefore 0x0090581f.
